Restoring a German Helmet ? We have what you need, a liner in nearly brand new condition. 
This liner was made by B&C in Litzmannstadt Ghetto in 1943 and shows very little use of wear. It is complete, with nice markings and suspenders. Litzmannstadt is the Łódź Ghetto in Poland, the second-largest ghetto in all of German-occupied Europe after the Warsaw Ghetto. Turned into an industrial site with Polish Jews and Romas and because of its remarkable productivity, the ghetto managed to survive until August 1944.
Behind this sad story, this piece has a huge historical value and is really rare.
